The Prime Rockford Fosgate M400 4D amplifier is a 400 Watt 4 channel high efficiency Class D amplifier specifically designed for Marine and Powersport/outdoor applications. Power ratings on Rockford Fosgate amplifiers conform to CEA 2006 industry standards. These guidelines mean your amplifier's output power ratings are REAL POWER numbers, not inflated marketing ratings.
The amplifiers printed circuit board is conformal coated with a UV resistant finish that conforms to industry standard UV and Salt Fog specifications, and the Class D circuit topology is so efficient, it consumes much less current, from your charging system, over traditional Class A/B amps.
